netfilter: nf_tables: nft_parse_register can return a negative value
Since commit 6e1acfa387b9 ("netfilter: nf_tables: validate registers
coming from userspace.") nft_parse_register can return a negative value,
but the function prototype is still returning an unsigned int.
Fixes: 6e1acfa387b9 ("netfilter: nf_tables: validate registers coming from userspace.")
